pip install xlwings 失败

Question

我使用的是 MacOS Mojave 版本 10.14.6、2.8 GHz Intel Core i7 处理器。 Python 版本：2.7.

“pip install xlwings”对我来说失败了。我试图通过使用 pip install -U setuptools

升级 setuptools 来解决这个问题

但是，这并不能解决问题。 “pip install xlwings”的完整错误信息如下：

xlwings declares appscript as a dependency but it doesn't limit version; appscript doesn't properly declare Python version compatibility (xlwings does it properly) 所以 pip 正在尝试安装与 Python 2.7 不兼容的最新版本。尝试以这种方式限制版本：

pip install "xlwings<0.17" "appscript<1.2"

pip install xlwings 失败

pip install xlwings fails

pip

xlwings
